Well, you asked GGB to identify where his feelings were localized in his body. "What feelings?" one might ask. How can you locate the feeling without knowing what the feeling is?
I think it's useful to identify the nuances in feeling. For example, I might say: "I feel sad," thinking that covers it. But looking at this list (or another one like it), I figure out that I feel "gloomy, dismal, heavy-hearted, abandoned." Those are very mournful words that seem to indicated a loss of something or someone. Or maybe I say, "I feel sad," but when I examine that general feeling more closely, I realize that I feel "hopeless, helpless, confused, wishy-washy," which seem to be about my judging myself as incompetent and a failure at something.
I can say "I feel BAD..." but that covers a lot of territory. Anger can be anything from annoyance, disdain, contempt to murderous rage...
